• The process list sorts by CPU again after the first reading, and rows for the same background process show which PID they are.

Little Mac Stats 0.3.0

Mac Stats is now Little Mac Stats, part of the little family with Little Worker and Little CI.

• New name, app icon, and artwork: the meter character, with three meter bars on its head.
• New bundle identifier (com.thelittleworker.little-mac-stats), update feed, update-signing key, and Homebrew cask (parkerrex/tap/little-mac-stats).

This is a clean break. Mac Stats 0.2.0 and earlier will not update to this release through Check for Updates. Quit and delete Mac Stats, then install Little Mac Stats. Saved settings do not carry over. Homebrew users can run brew update and brew upgrade --cask parkerrex/tap/little-mac-stats.
